The Love Actually actress, 38, is expecting her first child with her husband, musician Jay McManus, 30. In an interview with Hello! magazine, Martine said that the pregnancy came as a complete shock, as she didn’t know she would be able to conceive a baby.

‘We’d always said that if we were fortunate to be blessed with a child, that would be wonderful, but we were very aware that it’s not a given,’ says Martine. ‘As a woman in her late 30s who’s experience health problems, I thought I might have to accept that it wasn’t a path my life was going to take.

‘But it would have been a great sadness in our lives if that had been the case,’ Martine continues.

Fortunately, the actress, who’s battle with depression and chronic fatigue syndrome has left her unable to work, has now got her chance at motherhood. Martine’s already into her second trimester of pregnancy and her due date is Valentine’s Day next year.

‘It’s like finally the tides have turned,’ says Martine. ‘Great things are starting to happen on the work front, but more than anything, expecting our baby boy has given us clarity about what matters.’

We love a good pregnancy announcement here at Mother&Baby — some have definitely taken us (and, in some cases, the celebrities themselves) by surprise. From Halle Berry's joy at getting pregnant at 46, to Mila Kunis and Ashton Kutcher expecting their first child together, we've picked out some of the biggest shocks from the past year.
